That wouldn't end Bitcoin. It might make some trouble, but even that wouldn't that big.
Even if you could drop the hashrate 50%(which is complete bullshit, since if it drops miners with older hardware just go in again), that just means double confirmation time. So what? It adjust after 4 weeks instead of 2 weeks, big deal ...

why would miners with old gear go in on high difficulty? The hashrate doesn't make a difference for them, the difficulty does.
Well, we assume a further decline as time passes eventually leading to everyone drop out.

And there you are wrong. The overall hashrate tells them if they find the block or somebody else finds the block. The difficulty just tells them how long it will take them(or someone else) to find it.
Why would we assume a further decline? Everybody knows, that there will be a new adjustment in 4 weeks max.

the situation would be: high difficulty stuck and low hashrate
clones of bitcoin died this way before.

The Bitcoin network is much stronger than that of his clones. You can't really compare them.
There are even people in the network, who still mine for the fun of it or just to support Bitcoin, not to make a profit.

sure. The way presented here makes it affordable though.
The few hobbyminers left will not want to mine if they can't even find a block in a day.

Do you really think, professional miners would trash their expensive hardware, they can't use for anything else than mining, when the difficulty goes up? That would be pretty stupid from an economical POV.
